ADS7142IRUGT is an Analog to Digital Converter (ADC) provided by Texas Instruments operating in a wide range of applications including industrial, automotive, audio, robotics, and medical. This ADC is designed with a converter core voltage of 3V, providing a sampling rate of 32MSPS (Megasamples Per Second), and is able to convert one 16-bit differential channel, or two 8-bit single ended channels into a 4-wire serial digital stream.The ADS7142IRUGT is capable of sensing thermocouples, strain gauges, bridge sensors, RTDs, isolated transducers and other industrial process control signals. This ADC offers high accuracy and is able to detect temperature in a range of -55°C to 150°C, utilizing an integrated temperature sensor. The power consumption in active mode for this device is 800mW, making it ideal for data acquisition applications where power efficiency is a priority.The datasheet for the ADS7142IRUGT offers a detailed look at the device’s operating parameters, such as the maximum input voltage range (2.5V), power supply voltage range (3V), sampling frequency (32MSPS), data bits (14/16-bit), offset error (0.5mV max), and SINAD (82dB typ). Other features of this device include an integrated low-noise PGA, wide input common mode range (1.2V to 3V), and fast start-up time (just 4.5μs).The ADS7142IRUGT is equipped with an integrated temperature sensor, making it ideal for thermocouple temperature sensors and RTDs. The datasheet recommends the use of the Texas Instruments ADS7106 or ADS7116 thermoelectric isolation amplifier (TIA) to isolate thermocouple temperatures from the rest of the board and reduce electromagnetic noise pickup.The ADS7142IRUGT also offers a wide range of GPIO (general purpose I/O) pins, allowing for the addition of or interfacing with a range of devices, including an SD card, PWM signals, encoders, and serial communication. This feature also allows for the addition of display and control devices for monitoring the output of an ADC. The ADC\'s digital and analog outputs can also be interfaced directly with a variety of microcontrollers and development boards.The working principle of the ADS7142IRUGT is fairly simple. The device first samples the analog input signal, then converts the signal into a digital signal using a 14/16-bit successive approximation register (SAR) ADC. The ADC records the input voltage and a 16-bit digital word is generated. The digital word is then transmitted using the device\'s 4-wire serial interface.The device\'s architecture, consisting of a high-speed SAR ADC and precision low noise PGA makes it ideal for a range of data acquisition tasks. It also has the ability to attenuate and amplify the signal before conversion, as well as performing analog-to-digital calibration and digital averaging.The ADS7142IRUGT analog to digital converter is a cost effective, reliable, and multi-purpose device providing precise measurement and conversion solutions for a variety of applications. The device is capable of sensing thermocouples, strain gauges, bridge sensors, RTDs, isolated transducers and other industrial process control signals with high accuracy, providing 16-bit data output with a sampling rate of 32MSPS. It is also equipped with a number of GPIO pins, as well as integrated low noise PGA, making it an ideal choice for a range of data acquisition tasks.
